About me

Turning ideas into scalable architectures.

Héctor Barbosa, Solutions Architect and CTO

With over 15 years in the tech industry, I have led the technical strategy of industry-leading companies such as Funidelia and Pepephone.

My experience spans everything from designing robust cloud architectures and cybersecurity to building and leading high-performing teams.

Specialized in scaling e-commerce and telecommunications platforms, I help companies build technology products that not only work, but grow alongside the business.

Now, as an independent professional, I bring this experience to companies looking to take the next step in their digital transformation.

Frequently asked questions

Everything you need to know.

  1. Q01
    What exactly does a solutions architect do?
    They design the technical structure of systems and digital products: which technologies to use, how they connect and how they scale. They translate business goals into concrete technical decisions.
  2. Q02
    When does my company need a CTO as a Service?
    When you need senior technical leadership but don't want—or can't justify—hiring a full-time CTO. Ideal for growth-stage startups, companies undergoing digital transformation, or projects with high technical complexity.
  3. Q03
    Do you work with companies in any sector?
    My specialty is e-commerce and telecommunications, though the methodology applies to any company that needs to scale its technology or modernize its stack.
  4. Q04
    What does it look like to start working together?
    A free diagnostic call, a proposed approach and budget, and project kickoff. The first deliverable typically lands within two weeks.
  5. Q05
    Do you work remotely or on-site?
    Primarily remote, for companies across Spain. Available for on-site sessions when the project calls for it.
  6. Q06
    Can I hire you for a one-off project, or only long-term?
    Both: one-off engagements such as technical audits or architecture design, and ongoing collaborations as CTO as a Service.
  7. Q07
    What's the difference between technical consulting and hiring a developer?
    A developer executes; a solutions architect decides what to build, how, and in what order. Technical consulting prevents costly design mistakes before a single line of code is written.
